Principle
The probe comprises of sense, shield and ground electrodes electrically isolated from the metallic tank by means of suitable insulators. The sense electrodes and the vessel wall serve as the two electrodes of an imperfect capacitor with the service material as the dielectric. A change in material level causes a change in admittance of this imperfect tank capacitors.
Benefits
- High durability and system reliability
- Suitable for very dusty environment
- Power Consumption: Less than 05 VA
- Calibration possible from remote location
- Shorter Probe Lengths
